JOHN F. POOL, OF FRIENDSVILLE, ILLINOIS.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 554,305, dated February 11, 1896.

Application filed April 30, 1895.

To all whom t may cori/ecrit:

Be it known that I, JOHN F. POOL, a citi- Zen of the United States, residing at Friendsville, in the county of Vabash and State of Illinois, have invented a new and useful Sash- Fastener, of which the following is a specification. r

This invention relates to an improvement in devices for supporting window-sashes at various heights, and has for its object to simplify and improve the construction of sashfasteners and to provide an invisible device which will operate automatically to hold the sash of a car-window at any desired height, and also operate automatically to allow the sash to be lowered.

The invention consists in certain novel features and details of construction and arrangement of parts, as hereinafter fully described, illustrated in the drawings and pointed out in the claims.

In the drawings, Figure l is a perspective view of arailroad-car window-sash constructed in accordance with the present invention. Fig. 2 is a similar view of a portion of a carwindow casing, showing the means for automatically operating the spring-catches carried by the window-sash. Fig. 3 is a vertical section through a window sash and casing, illustrating the operation of the improved device. Fig. 4C is an enlarged edge view of a portion of the window-sash, showing the form and arrangement of the pivoted spring-catch.

Similar numerals of reference designate `corresponding parts in all the figures of the drawings. j

Referring to the drawings, l indicates an ordinary railway-coach window-sash, which for the purposes of applying this invention is cut out ornotehed upon either side edge,

as shown at 2, for the reception of an oppositely-disposed pair of spring-catches 3, each pivoted at its upper end and provided at its lower end with an outward bend or foot 4:. These catches are made preferably from fiat strips of sheet-steel, and when in their normal position assume the position indicated in Fig. l, with their feet projecting laterally beyond the side edges of the window-sash in position adapting them to engage the inner adjacent faces of the window-casing.

The window-casing (designated at 5) is pro- Serial No. 547,681. (No model.)

vided in the inner adjacent faces of its upright portions with a series of staples G and with notches 7, adjacent to and just above or extending upwardly from said staples. The window-casing is further provided at either side above the series of staples 6 with inclined deflecting tracks 9, composed, preferably, of staples or made from a piece of wire provided with inturned ends or points adapted to penetrate the wood, and thereby to hold said staple or wire in place. These tracks 9` incline downwardly from the rear part of the groove in which the window-sash travels to a point approximately in the center thereof, while a similar pair of staples or inclined tracks l0 are arranged below the series of staples 6 and inclined downwardly from the front edge of the window-groove toward the center thereof, as shown.

In operation, as the sash is lifted the springcatches 3 engage the staples 6 or the notches 7 with their outwardly-projecting feet 4. Any number of staples or notches maybe provided according to the number of adjustments which it is desired to provide for the sash. When it is desired to lower the sash, the latter is pushed all the way to the top of the casing until the feet of the spring-catches 3 pass above the upper inclined staples or tracks 9. Then as the sash is drawn downward said inclined tracks serve to deflect the feet of the spring-catches from their course and throw them to the opposite side of the groove in which the sash travels, which, being smooth, as shown, permits the sash to be carried all the way down. J ust before reaching the window-sill the feet of the spring-catches come into contact with the lower pair of inclined tracks or staples lO, and are thereby again defiected until they are brought into vertical line with the staples or notches above described.

It may be here stated that it is preferred to use both the staples 6 and notches 7 as shown in the drawings, the notches serving as recesses for the feet of the spring-catches to enter and the staples forming metallic rests for said feet, thereby preserving the proper working condition of the window-casing for a greater length of time. It will be apparent,

however, that the notches may be dispensed with and the staples made to project slightly IOO outside of the face of the window-casing, or the staples may be dispensed with and the notches only employed, Without departing from the spirit of this invention.

The device above described is simple and inexpensive in construction, durable in practice, automatic in operation, and will be found reliable and eflicicnt in use. It will be apparent also that the device is applicable to the Windows of ordinary dwelling-houses, stores, &c.

Various changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention7 what is claimed, and desired to be secured by Letters Patent, is-

l. In asash-fastening device, the combination With a sash, of a movable catch located in the side edge thereof, the WindoWcasing provided with a series of notches or stops for engaging said catch, and inclined tracks or deiiectors arranged above and beneath said series of notches or stopsand arranged to operate upon said catch for throwing the latter into and out of the plane of said notches or stops in the window-casing, substantially as specified.

2. In a fastening device 'for Window-sashes, the combination with a sash, of a pivoted catch, the Window-casing provided With a vertical series of ledges with Which said pivoted catch is adapted to engage for holding the sash at various heights, and a deflector for moving said pivoted catch out of alignment With said ledges, substantially as and for the purpose described.

In testimony that I claim the foregoing as my oWn I have hereto affixed my signature in the presence of two Witnesses.
